Phase 1 - Downtown Area

Phase I consists of the following: construction of a combination of gravity sewers and low-pressure sewers to service the Downtown Area; construction of a wastewater treatment facility (WWTF); and installation of the effluent disposal system.  The WWTF will be constructed at the former Tri-Town Septage Treatment Facility on Overland Way; this facility has been demolished as of April 2019.  The figure below shows the layout of the collection system, pumping stations, site of the WTTF, and site of the effluent disposal system.Test 1
